River Whispers chronicles her solitary boat journey through the wilderness, during which she finds companionship, falls into mortal danger, and recalls a long-forgotten violent death. The tall tales of river life she heard as a child come back to haunt her as she slowly recognizes the awful truth of her grandmother's life.
